Proteomics (11)17 2011
Abstract
Lactobacillus acidophilus NCFM is a probiotic bacterium adapted to survive in the gastrointestinal tract and with potential health benefits to the host. Lactitol is a synthetic sugar alcohol used as a sugar replacement in low calorie foods and selectively stimulating growth of L. aci...

Abstract
We report that, in the rat hippocampus, learning leads to a significant increase in extracellular lactate levels that derive from glycogen, an energy reserve selectively localized in astrocytes. Astrocytic glycogen breakdown and lactate release are essential for long-term but not short-term memory f...

Abstract
We describe techniques for measuring the amount and activity of Rubisco in higher plants. To accommodate a range of experimental capabilities, we describe basic radioisotopic methods as well as non-radioactive techniques. The required calculations are included. We discuss problems that commonly aris...

Abstract
Abstract
The polyol isomalt (Palatinit) is a very low glycaemic sugar replacer. The effect of food supplemented with isomalt instead of higher glycaemic ingredients like sucrose and/or starch hydrolysates on metabolic control in patients with type 2 diabetes was examined in this open study. Thirty-three pati...

Abstract
Apatite cement containing porogen can be a useful material for the fabrication of biporous (macro- and microporous) apatite, which has gained much attention as a bone substitute material because of its large surface area and that it improves cell penetration. In the present study, the effects of add...

Abstract
Our present study provides evidence that interaction of CD24 with the cell adhesion molecule L1 is mediated by O-linked glycans carrying alpha2,3-linked sialic acid. Furthermore, de-N-glycosylated CD24 was shown to promote or inhibit neurite outgrowth of cerebellar neurons or dorsal root ganglion ne...

Polyol synthesis of silver nanoparticles: mechanism of reduction by alditol bearing polysaccharides.
Abstract
Alditol bearing chitosans have shown the ability to reduce silver ions in mild conditions and without addition of exogenous reducing agents. The ion reduction induces the formation of a lactone moiety on the polysaccharide (Fetizon reaction) without causing C-C bond cleavage on the p...

Analysis of methylated O-glycan alditols by reversed-phase NanoLC coupled CAD-ESI mass spectrometry.
Abstract
The structural diversity of mucin-type O-glycans (O-GalNAc core-based) exceeds that of N-linked glycans by far. Structural analysis of this type of protein modification is hampered, however, by the unavailability of specific endo-acetylgalactosaminidases that would cleave the intact oligosaccharide...
